STRAW-STACKER ATTACH M ENT FOR TH RASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 284,507, dated September 4, 1883. t Application filed June 2, 1883 (No model.)

To all whom it may concern:

Be it known that we, DUDLEY l). SPRAGUE, of California, Moniteau county, State of Mis souri, and PEARLEY J. SPRAGUE, of Higbee, Randolph county, Missouri, have invented a certain new and useful Improvement in Straw- Stacker Attachments for Thrashing-Machines, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, and in which.

Figure 1 is aside elevation. Fig. 2 is a top view, parts broken away. Fig. 3 is a diagram, and Figs. 4, 5, and 6 enlarged detail views illustrating different parts.

Our present invention relates to means for connecting the stacker to the machine; and it.

rear end of a thrashing-machine, and B B the sills of the machine. To the sills are connected folding beams or pieces 0 C, by means of stirrups D D, whose upper and lower ends fit in sockets of journal brackets or boxes E E, secured to the sills andbeams, respectively,

preferably two foreach end of the stirrup, as

shown in Fig. 6. 'Thestirrups preferably consist of simple links, as shown in Fig. 4, and the preferred form of bracket is illustrated in Fig. 5. Thebeams or pieces 0 extend some distance toward the front of the machine from the points of bearing of the stirrups, so that when in their normal position (shown in Fig. 1) they will be held in ahorizontal positionor, mother words, their outer ends will be supported by their inner ends bearing against The stirrups are placed near the ends of the sills, so that the outer ends of the beams can be turned up, as shown in the diagram, Fig. 3. To the outer ends of the beams is connected the stacker F, either directly, or, as shown and preferred, through means of the turn-table or frame G, to which the stacker is attached, and a circular track,

, H,wl1ich supports the turntable, and which secured to the outer ends of the beams. When the beams are in their lower or normal position they are self-supporting, as stated, not 'requir-.

ing legs or requiring to be connected to the rear end of the machine by chains or ropes, and can be conveniently folded up when desired.

We do not confine ourselves to the exact form of beams shown, for a frame-work with projections corresponding to the inner ends of the beams, with which the stirrups would connect, would answer the same purpose, the frame supportingthe track or the stacker being secured directly to the frame; or the beams may be mere side pieces of a frame-work.

We have shown a cross-piece, K, between the outer ends of the beams, and a crosspiece, L, between them near the stirrups (see Fig. 2) to which former the necessary driving-gearing may be secured, and to the latter of which the track may be connected by a bolt, N. y 7

O 0 represent stops or bearing-blocks, against which the inner ends of the beams bear when in their normal position. They are secured to the machine, and act to keep the beams parallel with the sills and from moving inward too far, or from having a tendency to do so.

We claim as our invention- 1. In a straw-stacker attachment for thrashing-machines, the. combination of the frame, the stacker, the folding self-supporting beams to which the stacker is attached, and the stopblocks, as set forth. i

2. In a stacker attachment for thrashingmachines, the combination of the frame, the stacker, two beams, to whose outer portions the stacker is attached, and suitable stirrups connecting said beams to the machine, said beams being adapted to be folded up and to be self-supporting when in their normal position, substantially as shown and deconnected to the sills, all arranged and ,operscribed. h ating substantially as shown and described.

3. In combination with the sills of a t rash- 7 ing-machine and a stacker attachment, the 5 folding self-supporting beams to which the a stacker is attached, as described, and stir- In presence 0frups or links and suitable journal brackets GEO. H. KNIGHT, or boxes, by means of which said beams are J os. WAHLE.
